Abstract: A high-gloss, corrosion-resistant coating which can be applied directly to surface comprising about 30 to 82 percent by weight of a polymeric binder and 18 to 70 percent by weight of a pigment system consisting essentially of zinc molybdate, zinc salt of benzoic acids, and zinc phosphate in specific ratio's. The coating exhibits good adhesion, flexibility, chemical- and weather-resistance.

Abstract: A coating for metallic or polymeric composite substrates is disclosed which erforms both as a primer and as a topcoat. It comprises a two component aliphatic polyurethane binder, with titanium dioxide, zinc molybdate, zinc phosphate, an organo-zinc salt, and titanium dioxide vesiculated bead pigments in controlled amounts. The coating exhibits good adhesion, corrosion inhibition, flexibility, chemical and weather resistance, and opacity.

Abstract: A water-displacing paint is disclosed for coating metallic surfaces in hu environments to prevent corrosion. The paint comprises controlled proportions of a silicone alkyd resin to serve as a binder and physical barrier, solvents including ethyl acetate, aromatic mineral spirits and 1,1,1 trichlorotrifluorethane for ensuring water immiscibility, a petroleum sulfonate to inhibit corrosion and aid surface absorption, and an organo-titanate of isopropyl tri-titanate to promote surface adhesion. Selected amounts of titanium dioxide and zinc molybdate are included as pigments in one effective example of the paint to provide it a white color. Alternate colors may be produced conventionally by adding standard tinting pigments in amounts sufficient to yield the desired color.
